• How do I pipe the Java console output to a file?

  - by Ced

  I found a bug in an application that completely freezes the JVM. The produced stacktrace would provide valuable information for the developers and I would like to retrieve it from the Java console. When the JVM crashes, the console is frozen and I cannot copy the contained text anymore. Is there way to pipe the Java console directly to a file or some other means of accessing the console output of a Java application? Update: I forgot to mention, without changing the code. I am a manual tester. Update 2: This is under Windows XP and it's actually a web start application. Piping the output of javaws jnlp-url does not work (empty file).

• Using injected EntityManager in class hierarchies

  - by Emre Sahin

  The following code works: @Stateless @LocalBean public class MyClass { @PersistenceContext(name = "MyPU") EntityManager em; public void myBusinessMethod(MyEntity e) { em.persist(e); } } But the following hierarchy gives a TransactionRequiredException in Glassfish 3.0 (and standard JPA annotations with EclipseLink.) at the line of persist. @Stateless @LocalBean public class MyClass extends MyBaseClass { public void myBusinessMethod(MyEntity e) { super.update(e); } } public abstract class MyBaseClass { @PersistenceContext(name = "MyPU") EntityManager em; public void update(Object e) { em.persist(e); } } For my EJB's I collected common code in an abstract class for cleaner code. (update also saves who did the operation and when, all my entities implement an interface.) This problem is not fatal, I can simply copy update and sister methods to subclasses but I would like to keep all of them together in a single place. I didn't try but this may be because my base class is abstract, but I would like to learn a proper method for such a (IMHO common) use case.

• How can I prevent users from taking screenshots of my application window?

  - by Midday

  What are some methods to prevent screenshots from being taken, if any? I've considered setting the "Print Screen" button as a hotkey, which makes the window fuzzy. However, there would be the problem of other 3rd party screenshot tools. How can I prevent their use? Why would I want such a thing? The idea is to create a chat client which you can't share the chatted information with others, not by copy & paste nor by print screen... Looking for general ideas or suggestions rather than actual code.

• Addressing "Access Denied" Exception with WMI Calls

  - by Joe

  I'm getting an exception with a message of "Access Denied" when executing against a WMI request. Some WMI requests appear to require higher security privileges than others. Ultimately my goal is to monitor process launches within the system and log. Regardless if there is a better approach, its now become a vendetta in getting this WMI approach to work. I've attempted the code at Security Tools - WMI Programming Using C#.Net and still receive the exception. If you copy the code found in the blog entry you can reproduce my issue. Another post on a similar topic can be found at link text but again, try the code and you'll the see the same security exception. How do I permit my code to execute these WMI requests? I'm running on Windows 7 Pro and VS 2010 in a new C# command line project.

• How can you write a function that accepts multiple types?

  - by matthy

  I have a function that should work on int[] and on String[] now i have made the same function with a int parameter and an String parameter however if it has to go this way its a bit copy paste work and doesn't look very organized is there a way to solve this and put these 4 functions in 2? static public void print(String s) { System.out.println(s); } static public void print(int s) { System.out.println(s); } static public void printArray(String[] s) { for (int i=0; i<s.length; i++) print(s[i]); } static public void printArray(int[] s) { for (int i=0; i<s.length; i++) print(s[i]); } Thanks Matthy

• Is using GET with a tokenID for security a good idea?

  - by acidzombie24

  I was thinking about this and it appears POST only a little less vulnerable and somewhat harder (do to requiring the user to click something). I read about token ids and double submitted cookies and i am not sure what the difference is http://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet#Disclosure_of_Token_in_URL http://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet#Double_Submit_Cookies Right now i have the user id (PK in my table) and a session id so you cant simply change your cookie ID and act like someone else. Now it seems like i put the session id as a token in each of my forms and check them bc attackers cant guess these tokens. However i dislike the idea of putting the session id into the page for ppl to see. But really, is there a problem with that? short of having the user copy/pasting the html is there any attacks that can happen due to the session id being in plain view in html?

• Top techniques to avoid 'data scraping' from a website database

  - by Addsy

  I am setting up a site using PHP and MySQL that is essentially just a web front-end to an existing database. Understandably my client is very keen to prevent anyone from being able to make a copy of the data in the database yet at the same time wants everything publicly available and even a "view all" link to display every record in the db. Whilst I have put everything in place to prevent attacks such as SQL injection attacks, there is nothing to prevent anyone from viewing all the records as html and running some sort of script to parse this data back into another database. Even if I was to remove the "view all" link, someone could still, in theory, use an automated process to go through each record one by one and compile these into a new database, essentially pinching all the information. Does anyone have any good tactics for preventing or even just dettering this that they could share. Thanks

• default maven compiler setting

  - by Jeeyoung Kim

  Hello Maven gurus, Right now, I'm writing a small java application by my own, with few maven pom.xml files. I want to make all my maven packages to compile with jdk 1.6, and I can't find a good way to do it without manually setting it on every single POMs - I'm sick of copy-and-pasting <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> in every single pom.xml file I generate. Is there a simpler way to resolve this issue?

• Is a successor for TeX/LaTeX in sight?

  - by Mnementh

  TeX/LaTeX is great, I use it in many ways. Some of it's advantages are: it uses text files, this way the input-files can be diffed and many tools exist to work with text it is very flexible it has a stable layout: if I change something at the start of the document, it doesn't affect other things at the end of the document it has many extensions to reach different goals (a successor would start without extensions, but would have a good extension-system) you can use standard build control tools to support complicated documents (thanks dmckee) you can encapsulate solutions and copy&paste them to new documents or send them to others to learn from (thanks dmckee) But on the other hand some little things are not so good: it is hard to learn at the beginning it is complicated to control position of images a few things are a little counter-intuitive sometimes you have to type too much (begin{itemize} ... \end{itemize}) So, does there exist a successor/alternative to LaTeX or at least is some hot candidate for an alternative in development. A real successor/good alternative would keep the advantages and fix the disadvantages, or at least some of them.

• Excel 2003 VSTO convert to PDF

  - by KClough

  I have an excel workbook vsto solution that needs to generate a pdf copy of one of its sheets as output. I have a license for abcdpdf .net and tried outputting to html, then using abcpdf to convert the html to pdf, but the excel html markup tries to emulate excel with all 4 worksheets with horrible markup. It also messes up the colors (silver background across entire workbook). Any suggestions? Here is the code I'm currently using to generate the html file: FileInfo excelDoc = new FileInfo(Globals.ThisWorkbook.Path + @"\Document.html"); Globals.Sheet2.SaveAs(excelDoc.FullName, Excel.XlFileFormat.xlHtml, missing, missing, false, false, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing); If I hack away some of the html header tags manually, I can get abcdpf to accept it, but the formatting is a bit off and this solution seems sub optimal. Thanks in advance.

• Synchronising local and remote DB

  - by nico

  Hi everyone, I have a general question about DB synchronisation. So, I'm developing a website locally (PHP + MySQL) and I would like to be able to synchronise at least the structure (and maybe the contents) of the two DB when one of the two is changed (normally I would change the local copy). Right now what I'm doing is to use mysqldump to dump the modified tables and then import them in the remote DB or do it by hand if the changes are minimal. However I find this tedious and error-prone. For the PHP I'm currently using Quanta+ which has the handy feature of finding files that have changed and just upload those. Is there something similar for MySQL? Otherwise how do you keep your DBs synchronised? Thanks nico PS: I'm sorry if this was already asked, I saw other questions that deal with similar topics, but couldn't really find an answer.

• SharePoint - DIP problem on local copies downloaded from the portal

  - by user255234

  Our users have issues where the Document Information Panel(DIP) appears on Word, Excel, PPT documents. Here is the scenario: User downloads a copy of a template from the portal to his/her local hard drive. User edits that template and renames the file, again saving it to his/her local drive. User continues to edit and update that new document, and it continues to prompt him/her for document information as if the user was saving it on the portal. User clicks the “X” to remove this DIP bar, the next time he/she opens the local file it comes back. Is there anything I can do to make the DIP NOT SHOW on the local copies? Thanks!

• Comparing 2 mysql tables and updating only records that have changed

  - by Roland

  I have the following. Two mysql tables. I want to copy info that has changed from table a to b. For example if row 1 column 2 has changed in table a I want to only update that column in table b. Table b is not the same as a but has same columns that also exist in a. The other solution I have is to just clear table b and replace it with the contents from table a, the problem with this could be that the script will take longer to execute, since there are more than 10000 records. Any advise for which method would work the best will be highly appreciated

• During Spring unit test, data written to db but test not seeing the data

  - by richever

  I wrote a test case that extends AbstractTransactionalJUnit4SpringContextTests. The single test case I've written creates an instance of class User and attempts to write it to the database using Hibernate. The test code then uses SimpleJdbcTemplate to execute a simple select count(*) from the user table to determine if the user was persisted to the database or not. The test always fails though. I was suspect because in the Spring controller I wrote, the ability to save an instance of User to the db is successful. So I added the Rollback annotation to the unit test and sure enough, the data is written to the database since I can even see it in the appropriate table -- the transaction isn't rolled back when the test case is finished. Here's my test case: @ContextConfiguration(locations = { "classpath:context-daos.xml", "classpath:context-dataSource.xml", "classpath:context-hibernate.xml"}) public class UserDaoTest extends AbstractTransactionalJUnit4SpringContextTests { @Autowired private UserDao userDao; @Test @Rollback(false) public void teseCreateUser() { try { UserModel user = randomUser(); String username = user.getUserName(); long id = userDao.create(user); String query = "select count(*) from public.usr where usr_name = '%s'"; long count = simpleJdbcTemplate.queryForLong(String.format(query, username)); Assert.assertEquals("User with username should be in the db", 1, count); } catch (Exception e) { e.printStackTrace(); Assert.assertNull("testCreateUser: " + e.getMessage()); } } } I think I was remiss by not adding the configuration files. context-hibernate.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd> <bean id="namingStrategy" class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"> <property name="staticField"> <value>org.hibernate.cfg.ImprovedNamingStrategy.INSTANCE</value> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="destroy" scope="singleton"> <property name="namingStrategy"> <ref bean="namingStrategy"/> </property> <property name="dataSource" ref="dataSource"/> <property name="mappingResources"> <list> <value>com/company/model/usr.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.use_sql_comments">true</prop> <prop key="hibernate.query.substitutions">yes 'Y', no 'N'</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.use_minimal_puts">false</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.current_session_context_class">thread</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> <property name="nestedTransactionAllowed" value="false" /> </bean> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager"> <ref local="transactionManager"/> </property> <property name="transactionAttributes"> <props> <prop key="create">PROPAGATION_REQUIRED</prop> <prop key="delete">PROPAGATION_REQUIRED</prop> <prop key="update">PROPAGATION_REQUIRED</prop> <prop key="*">PROPAGATION_SUPPORTS,readOnly</prop> </props> </property> </bean> </beans> context-dataSource.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="org.postgresql.Driver" /> <property name="jdbcUrl" value="jdbc\:postgresql\://localhost:5432/company_dev" /> <property name="user" value="postgres" /> <property name="password" value="postgres" /> </bean> </beans> context-daos.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="extendedFinderNamingStrategy" class="com.company.dao.finder.impl.ExtendedFinderNamingStrategy"/> <bean id="finderIntroductionAdvisor" class="com.company.dao.finder.impl.FinderIntroductionAdvisor"/> <bean id="abstractDaoTarget" class="com.company.dao.impl.GenericDaoHibernateImpl" abstract="true" depends-on="sessionFactory"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> <property name="namingStrategy"> <ref bean="extendedFinderNamingStrategy"/> </property> </bean> <bean id="abstractDao" class="org.springframework.aop.framework.ProxyFactoryBean" abstract="true"> <property name="interceptorNames"> <list> <value>transactionInterceptor</value> <value>finderIntroductionAdvisor</value> </list> </property> </bean> <bean id="userDao" parent="abstractDao"> <property name="proxyInterfaces"> <value>com.company.dao.UserDao</value> </property> <property name="target"> <bean parent="abstractDaoTarget"> <constructor-arg> <value>com.company.model.UserModel</value> </constructor-arg> </bean> </property> </bean> </beans> Some of this I've inherited from someone else.

• Python: Remove items from a list while iterating in Python

  - by xApple

  My problem is simple: I have a long list of elements that I want to iterate through and check every element against a condition. Depending on the outcome of the condition I would like to delete the current element of the list, and continue iterating over it as usual. I have read a few other threads on this matter. Two solutions seam to be proposed. Either make a dictionary out of the list (which implies making a copy of all the data that is already filling all the RAM in my case). Either walk the list in reverse (which breaks the concept of the alogrithm I want to implement). Is there any better or more elegant way than this to do it ? def walk_list(list_of_g): g_index = 0 while g_index < len(list_of_g): g_current = list_of_g[g_index] if subtle_condition(g_current): list_of_g.pop(g_index) else: g_index = g_index + 1

• readobject method throws ClassNotFoundException

  - by eruina

  Hi all, I'm trying to pick up Java and wanted to test around with Java's client/server to make the client send a simple object of a self defined class(Message) over to the server. The problem was that I kept getting a ClassNotFoundException on the server side. I think the rest of the codes seem to be alright because other objects such as String can go through without problems. I had two different netbeans projects in different locations for client and server each. Each of them have their own copy of Message class under their respective packages. Message class implements Serializable. On the client side, I attempt to send a Message object through. On the server side, upon calling the readObject method, it seems to be finding Message class from the client's package instead of it's own. printStackTrace showed: "java.lang.ClassNotFoundException: client.Message" on the server side I have not even tried to cast or store the object received yet. Is there something I left out?

• Using device variable by multiple threads on CUDA

  - by ashagi

  I am playing around with cuda. At the moment I have a problem. I am testing a large array for particular responses, and when I get the response, I have to copy the data onto another array. For example, my test array of 5 elements looks like this: [ ][ ][v1][ ][ ][v2] Result must look like this: [v1][v2] The problem is how do I calculate the address of the second array to store the result? All elements of the first array are checked in parallel. I am thinking to declare a device variable int addr = 0. Every time I find a response, I will increment the addr. But I am not sure about that because it means that addr may be accessed by multiple threads at the same time. Will that cause problems? Or will the thread wait until another thread finishes using that variable?

• How would you start automating my job? - Part 2

  - by Jurily

  (Followup to this question) After surviving the first wave of incoming shipments (9 hours of copy/paste), I now believe I have all the requirements. Here is the updated workflow: Monkey collects email attachments (4 Excel spreadsheets, 1 PDF) Monkey creates central database, does complex calculations (right now this is also an Excel spreadsheet) Monkey sends data to two bosses, who set the retail prices independently; first one to reply wins Monkey sends order form to our other warehouses, also Excel Monkey sends spreadsheets to VIP customers, carefully sanitized and formatted (4 different discount categories) Jurily enters the data into the accounting system. I've given up on automating this part, there's too much business logic involved, and the database is a pile of sh^W legacy My question: What technologies would you use for a quick and dirty solution? I'm mostly sold on C#, but coming from a Linux/C++ background, I'm horribly confused about my choices in Microsoft-land. For bonus points: How would you redesign the whole system from the ground up? P.S. in case you were wondering, my job title is System Administrator.

• Can documents indexed with Solr on JDK6 be retrieved using only lucene api on JDK1.4?

  - by huynhjl

  My runtime environment is still on JDK1.4 but I like the Solr features related to how documents are ingested and indexed. Would I be able to index my documents using Solr offline on a recent version of the JDK, copy the index over and use it in my runtime environment with an older version of the JDK? Version wise, Solr 1.4.0 uses Apache Lucene 2.9.1 which is JDK1.4 compatible. (but Solr itself requires JDK5). Assuming what I'm trying to do is even possible, what features would I lose if I search Solr indices only with the Lucene API?

• Reuse ASP.NET Control Multiple Times on Page

  - by macinjosh

  I feel somewhat foolish asking such a simple question, but I can't seem to find an answer. I'm new to ASP.NET (C#), but I'm learning by building a simple set of web pages that display a report. I have a variable that represents a company name. I need to output this variable in multiple places on the web page. The only way I have found to output a variable this is with: company_name.Text = "Acme Windows"; then <asp:literal id="company_name" runat="server" /> My problem is that I want to use company_name in multiple places on the page. Do I really have to create a separate variable holding the the same value for each time it is placed on the page? If I just copy the above XML code to all the places I want to show the variable it obviously creates a compile error since that ID is already defined. I feel like I'm missing something very obvious.

• Wireless barcode scanner

  - by Zinx

  Hi All, I have 2 wireless barcode scanners. I have created an application in C# which reads a barcode and sends data to a web service which then manipulates the data and do further processing. When I start aplication, it first tries to connect to web service and will proceed further only if connection succeded. The problem I am facing is, if I deploy the application through visual studio then it works fine and connects to web service. But if I just copy the contents (exe and config files) manually, then it gives error that unknown host name. Can someone please help me to understand how this connection works? Does it needs some special settings in scanner device which visual studio does automatically while deployment? Thanks and Cheers.
